Hi Ivan,
there is no direct integration of Morpheus into R (yet) but you may invoke a simulation from R that runs outside of R and then you import results from the logger files do your statistics in R.
In R you would use
system2("morpheus /path/to/model.xml", arg)
where arg may provide options like "--outdir /path/to/results/dir" (that dir must have been created before) and/or "--set symbol_of_model_parameter=value" (e.g. "--set k1=0.01") to set model parameter values from within R.
(And the same strategy works from Python.)
Best,
Lutz
